Attorneys: Interstate collapse suspect used as "scapegoat"

It didn't melt anything, it burned hot enough to weaken the joints where the sections are joined together. Then the weight made it collapse.

Negatory.......most bridge joints are not joined together anyway. They either have an expansion joint or a construction joint above nearly every column so they can move and flex a little with the weight of hundreds of cars and trucked crossing them.
When concrete is subjected to a roaring blaze like this the air in the concrete expands and explodes ,exposing the steel and pre stressed cables in these precast beams.
If you saw it on tv,there was concrete rubble on the Buford connector where the firefighters were BEFORE the bridge collapsed ,that was from the concrete being heated and popping
 
It wasn't PVC - it was HDPE which is highly flammable. And it was empty conduit, no FO, so the tubes did a great job of delivering air to the fire itself.
You are correct. Anybody can go on google earth and go to street level on the Buford connector and see how much roll pipe was under there. There was a lot.
